The present invention is directed to a goggle lens interchange system. More particularly, the present invention is directed to a goggle lens interchange system by which a lens of goggles may be easily removed and replaced, and a method of accomplishing the same.

2. Description of the Related Art

Currently, there are goggles on the market that offer replacement lenses for various light conditions. In such goggles, lenses are removed by sliding them out through a thin slot in the frame and replaced by sliding another or replacement lens into the thin slot in the frame. However, successfully inserting the lens into the thin slot is a difficult, precise, and time-consuming task, which cannot be successfully undertaken under adverse conditions, such as in cold weather, rain, ice, snow, in the dark, or when a user is wearing gloves, such as when skiing. Thus, up until now, goggles promoted as having interchangeable lenses have not been practical for use in the field, e.g., in cold or wet weather, or when a user is wearing gloves, such as when skiing. Therefore, there is a need for goggles that offer a user the ability to quickly and easily change lenses as needed under less than ideal conditions.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. The invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the figures, the dimensions of layers and regions may be exaggerated for clarity of illustration. Like reference characters refer to like elements throughout.

FIGS. 1A and 1B illustrate a goggle lens interchange system according to a first embodiment of the present invention.

As shown in FIGS. 1A and 1B, the goggle lens interchange system of the first embodiment of the present invention includes a frame 1 having a ledge 2 onto which a lens 3 is removably placed. The frame 1 opens, as shown in FIG. 1B, providing a rear portion 1 a and a front portion 1 b connected by a hinging mechanism 5. The hinging mechanism 5 allows the front and rear frame portions 1 b, 1 a to be disengaged on at least three sides thereof to allow access to the ledge 2 for easy lens replacement.

The lens of the first embodiment may include an outer lens separated from an inner lens by at least a gasket. In addition, there may be an air space between the outer and inner lenses. An example of such a lens is illustrated in FIG. 4A.

An exemplary method of operating the goggle lens interchange system of FIGS. 1A and 1B will now be described with respect to FIGS. 1C-1F.

As shown in FIG. 1C, the lens 3 is removably positioned on the ledge 2 (FIG. 1D), and the front and rear frame portions 1 b, 1 a are closed with the lens 3 sealed therebetween.

In FIG. 1D, the front frame portion 1 b is separated from the rear frame portion 1 a on three sides, providing access to the ledge 2. Movement of the front and rear frame portions is enabled by the hinging mechanism 5.

Access to the ledge 2, provided by separating the front and rear frame portions 1 b, 1 a, allows the lens 3 to be easily removed from the ledge 2, as shown in FIG. 1E. Another or replacement lens 3′ may then be positioned on the ledge 2 and the front and rear frame portions 1 b, 1 a closed, thereby easily providing a goggle having the lens 3′ sealed between the front and rear frame portions 1 b, 1 a, as shown in FIG. 1F.

Thus, by the present invention, a user is able to quickly and easily remove a lens and replace it with a different lens. Therefore, if, for example, a user is skiing and the sun begins to set, he or she may switch to a clear lens right on the lift or mountain, without having to return to the lodge, and without having to remove his or her gloves.

The goggle lens interchange system of the first embodiment may further include a locking mechanism (not shown) for holding the front and rear frame portions 1 b, 1 a together. The locking mechanism secures the front and rear frame portions 1 b, 1 a together with the lens 3 therebetween.

In this case, a user may unlock the locking mechanism, open the frame 1 revealing the ledge 2, remove the lens 3, place another or replacement lens such as lens 3′ onto the ledge 2, close the frame 1, and re-lock the locking mechanism quickly and easily even in extreme conditions, such as on the top of a snowy mountain, while wearing gloves.

FIG. 2 illustrates a goggle lens interchange system according to a second embodiment of the present invention. As shown in FIG. 2, the goggle lens interchange system of the second embodiment includes a rear goggle frame 10, having a ledge 2 onto which a lens 3 is removably placed, and at least one latch 40 moveably connected to the rear goggle frame 10 by a hinging mechanism 50, for removably securing the lens 3 to the rear goggle frame 10. The latch 40 opens to allow access to the ledge 2 for easy lens changes. Thus, similar to the first embodiment, a user may quickly and easily change lenses even in adverse conditions.

The lens in this embodiment may also include an outer lens separated from an inner lens by at least a gasket. In addition, there may be an air space between the outer and inner lenses. An example of such a lens is illustrated in FIG. 4A.

In FIG. 2, a latch 40, i.e., one, is shown on the right side, from a wearer's perspective, of the goggle frame. However, a position of a latch and/or a hinging mechanism of the present invention is not limited to what is shown in FIG. 2. For example, a similar latch and hinging mechanism may be disposed on the left side (from a wearer's perspective), a top, a bottom or any other portion of the goggle frame. In addition, as previously noted, there may be more than one latch and hinging mechanism, which may be disposed on right and left sides of the goggle frame, on a top and bottom of the goggle frame, or on any other combination of portions of the goggle frame.

FIGS. 5A and 5B illustrate a case where there are two latches 40A and two hinging mechanisms 50A disposed on right and left sides of a rear goggle frame 10A. The latches 40A open by swinging towards each other in an inward direction, thereby revealing the ledge 2.

Further, the hinging mechanism 50 is not limited to the position thereof illustrated in FIG. 2. That is, a latch may be disposed in the same position as the latch 40 of FIG. 2, but a hinging mechanism may be disposed at a middle portion of the latch, as opposed to being at end portions of the latch, as illustrated in FIG. 2. In such a case, the hinging mechanism would connect the latch to a middle portion, in the vertical direction, of a right side of the goggle frame.

FIG. 5C illustrates a case where there are two latches 40B and two hinging mechanisms 50B disposed at right and left sides of a rear goggle frame 10B. In the variation of the second embodiment shown in FIG. 5C, the hinging mechanisms 50B are positioned at a center, in the vertical direction, of the latches 40B and sides of the rear goggle frame 10B. In this case, the latches 40B open by swinging away from each other in an outward direction, thereby revealing the ledge 2.

In addition, in the present invention, a hinging mechanism may be disposed at any portion or portions of a latch, a pair of latches, or a plurality of latches, regardless of number, or placement, of the latch(es).

The goggle lens interchange system of the second embodiment, and variation thereof, may further include strap holder parts (not shown), which cover the latch or latches. In this case, by wearing the goggles, the latch(es) may be restrained from opening.

FIGS. 3A-3D illustrate a method of operating the goggle lens interchange system of FIG. 2.

As shown in FIG. 3A, the lens 3 is secured in place against the rear goggle frame 10 by the latch 40, which is attached to the rear goggle frame 10 by the hinging mechanism 50.

In FIG. 3B, the latch 40 is partially open, movement thereof being enabled by the hinging mechanism 50. Also shown in FIG. 3B is a locking mechanism 60, which may include a snap lock, wherein the latch 40 is provided with an edge that snaps into the locking mechanism 60 to be held securely in place. The edge of the latch 40 and the locking mechanism 60 may be formed of molded plastic or a semi-rigid material that allows the edge of the latch 40 to snap into or under the locking mechanism 60, which may be a groove formed into a side of the rear goggle frame 10.

In FIG. 3C, the ledge 2 is accessible by opening the latch 40 via the hinging mechanism 50, wherein the lens 3 is shown partially removed from the ledge 2 of the rear goggle frame 10.

In FIG. 3D, the lens 3 is completely removed from the rear goggle frame 10 and the ledge 2 is completely exposed. Thus, a different or a replacement lens (not shown) may be placed on the ledge 2 and the latch 40 may be closed by being swung on the hinging mechanism 50 and snapped into the locking mechanism 60 by a user. The method above applies equally, with minor variations, to a goggle interchange system of the present invention in which a number and/or placement of latch(es), hinging mechanism(s) and/or locking mechanisms(s) varies from those shown in FIGS. 2 and 3A-3D. For example, the method applies, with minor variations, to the goggle lens interchange system of FIGS. 5A-5C.

FIG. 4A illustrates a top perspective view of a goggle lens interchange system according to a third embodiment of the present invention.

As shown in FIG. 4A, a lens 3′, having an outer lens 3 a and an inner lens 3 b and an air space therebetween, is positioned on a molded ledge 6 of a rear goggle frame 10A, on top of foam 11 and a compressible gasket 12. A front f part of a goggle frame 10B is provided in such a manner as to be able to be in at least an open position, illustrated as 10D, or a closed position, illustrated as 10C. Movement of the front part 10B is provided for by a hinging mechanism 50, which also serves to connect the front part 10B to the rear goggle frame 10A. The front part in the closed position 10C compresses the foam 11 and compressible gasket 12, forming a seal between the lens 3″ and the molded ledge 6 of the rear goggle frame 10A. The front part in the closed position 10C may lock the lens 3″ in place by a snap, undercut, cam, or any other suitable locking mechanism. For example, the molded ledge 6 may include an undercut portion into which a molded edge of the front part 10B may be snapped when the front part is in the closed position 10C. In this embodiment, the foam 11 and/or compressible gasket 12 may act as a filter/gasket and a spring to allow the front part when closed 10C to cam over the lens 3″ and snap closed.

Although the lens 3″ illustrated in FIG. 4A includes the outer lens 3 a and the inner lens 3 b with an air space therebetween, the third embodiment is not limited to such a lens. Any appropriate lens may be used in any of the embodiments of the present invention.

FIG. 4B illustrates a variation of the third embodiment shown in FIG. 4A, in which the foam acts as a filter, a gasket, and a spring, as described with respect to FIG. 4A.

The goggle lens interchange system of the third embodiment and variants thereof may include more than one front part 10B. In addition, the goggle lens interchange system of the third embodiment may further include strap holder parts (not shown), which cover the front part or parts. In this case, by wearing the goggles, the front part or parts may be restrained from opening. Further, the front part or parts may be formed of a latch or latches, similar to those of the second embodiment, and may operate in a manner similar to that shown in FIGS. 3A-3D, with respect to the second embodiment.

In addition, features of the third embodiment may be included in the first and second embodiments, as well. For example, the ledge of the first and second embodiments may be a molded groove provided on top with foam and/or a compressible gasket. The foam and/or compressible gasket may be compressed between the front and rear frame portions or the rear frame portion and latch(es) to form a seal with the lens therebetween. The foam and/or compressible gasket may act as a filter or gasket, and may also act as a spring to allow the front portion(s) or latch(es) to cam over the lens and snap closed by means of a snap or cam or any other locking mechanism.

For example, the front portion(s) or the latch(es) may be provided with a molded rib 10 r and the rear frame portion with an undercut or undercuts 6 u to be locked together with a lens therebetween. Alternately, the front portion(s) or latch(es) may be provided with undercuts and the rear frame portion with a molded rib. Such molded rib and undercuts may serve to form a snap lock, whereby the front part(s) or latch(es) and the rear goggle frame may be locked together. The snap lock may work in a manner similar to a ball and socket, or a coffee cup and lid, to removably secure the lens therebetween. At least the molded rib and undercuts may be formed from semi-rigid molding materials that are flexible enough to allow such closures.

Although not shown in the drawings, in the above embodiments, latch(es) or front portion(s) of a goggle frame may be completely removed from the goggle frame or portion thereof by disengaging the hinging mechanism. In addition, a locking mechanism may be a snap, a cam, a latch or any other means by which the front and rear frame portions are locked together.
